|
|
A CLI tool and go library for generating a Software Bill of Materials (SBOM) from container images and filesystems.
|
|
|
|
|
|
|
|
**Features**
|
|
- Catalog container images and filesystems to discover packages and libraries.
|
|
- Supports packages and libraries from various ecosystems (APK, DEB, RPM, Ruby Bundles, Python Wheel/Egg/requirements.txt, JavaScript NPM/Yarn, Java JAR/EAR/WAR, Jenkins plugins JPI/HPI, Go modules)
|
|
- Linux distribution identification (supports Alpine, BusyBox, CentOS/RedHat, Debian/Ubuntu flavored distributions)
|
|
- Supports Docker and OCI image formats
|
|
|
|
If you encounter an issue, please [let us know using the issue tracker](https://github.com/anchore/syft/issues).
|
|
|
|
## Getting started
|
|
|
|
To generate an SBOM for a Docker or OCI image:
|
|
```
|
|
syft <image>
|
|
```
|
|
|
|
The above output includes only software that is visible in the container (i.e., the squashed representation of the image).
|
|
To include software from all image layers in the SBOM, regardless of its presence in the final image, provide `--scope all-layers`:
|
|
|
|
```
|
|
syft <image> --scope all-layers
|
|
```
|
|
|
|
Syft can generate a SBOM from a variety of sources:
|
|
```
|
|
# catalog a container image archive (from the result of `docker image save ...`, `podman save ...`, or `skopeo copy` commands)
|
|
syft path/to/image.tar
|
|
|
|
# catalog a directory
|
|
syft path/to/dir
|
|
```
|
|
|
|
The output format for Syft is configurable as well:
|
|
```
|
|
syft <image> -o <format>
|
|
```
|
|
|
|
Where the `format`s available are:
|
|
- `json`: Use this to get as much information out of Syft as possible!
|
|
- `text`: A row-oriented, human-and-machine-friendly output.
|
|
- `cyclonedx`: A XML report conforming to the [CycloneDX 1.2](https://cyclonedx.org/) specification.
|
|
- `table`: A columnar summary (default).
|
|
|
|
## Installation
|
|
|
|
**Recommended**
|
|
```bash
|
|
# install the latest version to /usr/local/bin
|
|
curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b /usr/local/bin
|
|
|
|
# install a specific version into a specific dir
|
|
curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b <SOME_BIN_PATH> <RELEASE_VERSION>
|
|
```
|
|
|
|
**macOS**
|
|
```bash
|
|
brew tap anchore/syft
|
|
brew install syft
|
|
```
|
|
|
|
You may experience a "macOS cannot verify app is free from malware" error upon running Syft because it is not yet signed and notarized. You can override this using `xattr`.
|
|
```bash
|
|
xattr -rd com.apple.quarantine syft
|
|
```
|
|
|
|
## Configuration
|
|
|
|
Configuration search paths:
|
|
|
|
- `.syft.yaml`
|
|
- `.syft/config.yaml`
|
|
- `~/.syft.yaml`
|
|
- `<XDG_CONFIG_HOME>/syft/config.yaml`
|
|
|
|
Configuration options (example values are the default):
|
|
|
|
```yaml
|
|
# same as -o ; the output format of the SBOM report (options: table, text, json)
|
|
output: "table"
|
|
|
|
# same as -s ; the search space to look for packages (options: all-layers, squashed)
|
|
scope: "squashed"
|
|
|
|
# same as -q ; suppress all output (except for the SBOM report)
|
|
quiet: false
|
|
|
|
log:
|
|
# use structured logging
|
|
structured: false
|
|
|
|
# the log level; note: detailed logging suppress the ETUI
|
|
level: "error"
|
|
|
|
# location to write the log file (default is not to have a log file)
|
|
file: ""
|
|
|
|
# enable/disable checking for application updates on startup
|
|
check-for-app-update: true
|
|
```
|
|
|
|
## Future plans
|
|
|
|
The following areas of potential development are currently being investigated:
|
|
- Add CycloneDX to list of output formats
|
|
- Establish a stable interchange format w/Grype
